Method for operating LED for representation of pictorial contents, involves providing operating device to operate light sources for blanking with current through light sources when no light setpoint signal lies for light sources

摘要

The method involves operating semiconductor light sources (501-505) with temporally changing current. An operating device (1) is provided for operating the light sources for blanking with current through the light sources when no light setpoint signal of a controller (3) lies for the light sources, where the current is equal to a preset minimum value. The minimum value is determined by repeated calibration that is comprised of steps of operating the light sources with current corresponding to zero. A measured variable of each light source is measured by a measuring unit (54). An independent claim is also included for a light generation arrangement for operating a semiconductor light source.
